Evaluation and development of functional resins and paints for drag-reduction in ships |
| 초록 |
A novel FDR-SPC(Frictional Drag Reducion-Self-Polishing Copolymer) was first synthesized in the previous study. The drag reducing functional radical such as PEGMA (Poly(ethylene)glycol methacrylate) has been utilized to participate in the synthesis process of the SPC. In the high-Reynolds number flow measurement with a flush-mounted balance and a LDV (Laser Doppler Velocimeter), the skin friction of the present FDR-SPC is found to be smaller than that of smooth plate throughout the range of Reynolds number, with the average drag reduction efficiency being 13.5% over the smooth plate. These results strongly support that the present FDR-SPC gives rise to the Toms effect based on chemical reaction at the surface of the coating.
